Abstract
A diagnostic for magnetic tape data storage drives and magnetic tape data storage cartridges comprises a magnetic tape data storage drive having more stringent servo error detection in write mode than in read mode. The magnetic tape data storage drive is set to a write mode, the write mode nominally for operating the write channel to write data while the track following servo apparatus detects and track follows the servo tracks of a magnetic tape; and scans the servo tracks of a magnetic tape in the write mode, but without writing data; detecting servo errors using criteria of the write mode; and logs information of the detected servo errors.
